Redneck vehicles often look like this... just the other day we saw one on the road much like this, that said "Redneck Woman" over the rear window.
Another Redneck thing, in my opinion, is to put homages to dead people in the rear window of your truck. A celebrity (preferably a NASCAR one), a relative, it doesn't matter: The sticker says "John Doe 1974-2009" on it. This is, in my opinion, bizarre.
Thou must also have the largest possible dog. A more aggressive dog is even better, and NINE or more aggressive dogs are even better than that!
Here's my first dog ever:
BIG, I tell ya! But he was a softie, squeaking his toys at strangers, which did NOT intimidate them at all...
Oh, he was a Rottweiller/Doberman/Shepherd mix, as far as we could tell. A very kindly and obedient dog.
